I guess it saves battery due to ARC (adaptive replacement cache).

ZFS is already quite old filesystem as has great features (for example: checksumming, snapshots, compression) that should be already standard.
Sure but if you don't know how zfs works do you really want to figure it out in the middle of trouble shooting installation problems, or post install root volume problems?
Isn't it similar to using mdraid, lvm and dm-crypt without experience?

In my other comments I suggested to not use ZFS for rootfs unless someone is already experienced.
Those are all pretty different, but yeah basically we agree on this. I'm not sure about battery life, if I had to give a more nuanced answer I would say it probably depends on use case and you should measure it if you want to be sure.
